algorithm, which is based on the 2011 v0.1 patch release and described in the
paper "Revisiting TCP Congestion Control using Delay Gradients" by David Hayes
and Grenville Armitage. It is implemented as a kernel module compatible with the
modular congestion control framework.
CDG is a hybrid congestion control algorithm which reacts to both packet loss
and inferred queuing delay. It attempts to operate as a delay-based algorithm
where possible, but utilises heuristics to detect loss-based TCP cross traffic
and will compete effectively as required. CDG is therefore incrementally
deployable and suitable for use on shared networks.

some general word-smithing.
- Don't claim that adaptive mutexes have a timeout (they don't).
- Don't treat pool mutexes as a separate primitive in a few places.
- Describe sleepable read-mostly locks as a separate lock type and add
them to the various tables.
- Don't claim that sx locks are less efficient. That hasn't been true in
a few years now.
- Describe lockmanager locks next to sx locks since they are very similar
in terms of rules, etc., and so that all the lock primitives are
grouped together before the non-lock primitives.
- Similarly, move the section on Giant after the description of all the
non-lock primitives to preserve grouping.
- Condition variables work on several types of locks, not just mutexes.
- Add a bit of language to compare/contrast condition variables with
sleep/wakeup.
- Add a note about why pause(9) is unique.
- Add some language to define bounded vs unbounded sleeps and explain
why they are treated separately (bounded sleeps only need CPU time
to make forward progress).
- Don't state that using mtx_sleep() is a bad idea. It is in fact rather
necessary.
- Rework the interaction table a bit. First, it did not include really
include sleepable rmlocks and it left out lockmgr entirely. To get
things to fit, combine similar lock types into the same column / row,
and explicitly state what "sleep" means. The notes about recursion
and lock order were also a bit banal (lock order is always important,
not just in the few places annotated here), so remove them. In
particular, the lock order note would need to be on just about every
cell. If we want to document recursion I think a better approach
would be a separate table summarizing the recursion rules for each
lock as having too many notes clutters the table.
- Tweak the tables to use less indentation so everything still fits with
the added columns.
- Correct a few cells in the context mode table.
- Use mdoc markup instead of explicit markup in a few places.

device names "md" or "md[0-9]*" and a "file" option are specified in
/etc/fstab like this:
md none swap sw,file=/swap.bin 0 0
- Add GBDE/GELI encrypted swap space specification support, which
rc.d/encswap supported. The /etc/fstab lines are like the following:
/dev/ada1p1.bde none swap sw 0 0
/dev/ada1p2.eli none swap sw 0 0
.eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.
swapctl(8) can understand an encrypted device in the command line
like this:
# swapctl -a /dev/ada2p1.bde
- "-L" flag is added to support "late" option to defer swapon until
rc.d/mountlate runs.
- rc.d script change:
rc.d/encswap -> removed
rc.d/addswap -> just display a warning message if $swapfile is defined
rc.d/swap1 -> renamed to rc.d/swap
rc.d/swaplate -> newly added to support "late" option
These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

- Add an rm_assert() supporting various lock assertions similar to other
locking primitives. Because rmlocks track readers the assertions are
always fully accurate unlike rw_assert() and sx_assert().
- Flesh out the lock class methods for rmlocks to support sleeping via
condvars and rm_sleep() (but only while holding write locks), rmlock
details in 'show lock' in DDB, and the lc_owner method used by
dtrace.
- Add an internal destroyed cookie so that API functions can assert
that an rmlock is not destroyed.
- Make use of rm_assert() to add various assertions to the API (e.g.
to assert locks are held when an unlock routine is called).
- Give RM_SLEEPABLE locks their own lock class and always use the
rmlock's own lock_object with WITNESS.
- Use THREAD_NO_SLEEPING() / THREAD_SLEEPING_OK() to disallow sleeping
while holding a read lock on an rmlock.

This is an extended version of ipv4_addr_IF which supports both IPv4 and
IPv6, and multiple range specifications. To avoid to generate too many
addresses, the maximum number of the generated addresses is currently
limited to 31.
- Add $ifconfig_IF_aliases, which accepts multiple IP aliases in a variable.
- ipv6_prefix_IF now supports !/64 prefix length. In addition to the old
64-bit format (2001:db8:1:1), a full 128-bit format like 2001:db8:1:1::/64
is supported.
- Replace ifconfig command with $IFCONFIG_CMD variable to support
a dry-run mode in the future.
- Remove IP aliases before removing all of IPv4 addresses when doing
"rc.d/netif down".
- Add a DAD wait to network6_getladdr() because it is possible to fail to
configure an EUI64 address when ipv6_prefix_IF is specified.
A summary of the supported ifconfig_* variables is as follows:
# IPv4 configuration.
ifconfig_em0="inet 192.168.0.1"
# IPv6 configuration.
ifconfig_em0_ipv6="inet6 2001:db8::1/64"
# IPv4 address range spec. Now deprecated.
ipv4_addr_em0="10.2.1.1-10"
# IPv6 alias.
ifconfig_em0_alias0="inet6 2001:db8:5::1 prefixlen 70"
# IPv4 alias.
ifconfig_em0_alias1="inet 10.2.2.1/24"
# IPv4 alias with range spec w/o AF keyword (backward compat).
ifconfig_em0_alias2="10.3.1.1-10/32"
# IPv6 alias with range spec.
ifconfig_em0_alias3="inet6 2001:db8:20-2f::1/64"
# ifconfig_IF_aliases is just like ifconfig_IF_aliasN.
ifconfig_em0_aliases="inet 10.3.3.201-204/24 inet6 2001:db8:210-213::1/64 inet 10.1.1.1/24"
# IPv6 alias (backward compat)

- "/etc/rc.d/routing start/stop <af> <if>" works as well. <af> cannot be

The NTB allows you to connect two systems with this device using a PCI-e
link. The driver is made of two modules:
- ntb_hw which is a basic hardware abstraction layer for the device.
- if_ntb which implements the ntb network device and the communication
protocol.
The driver is limited at the moment to CPU memcpy instead of using DMA, and
only Back-to-Back mode is supported. Also the network device isn't full
featured yet. These changes will be coming soon. The DMA change will also
bring in the ioat driver from the project branch it is on now.
This is an initial port of the GPL/BSD Linux driver contributed by Jon Mason
from Intel. Any bugs are my contributions.

These zones have slab size == sizeof(struct pcpu), but request from VM
enough pages to fit (uk_slabsize * mp_ncpus). An item allocated from such
zone would have a separate twin for each CPU in the system, and these twins
are at a distance of sizeof(struct pcpu) from each other. This magic value
of distance would allow us to make some optimizations later.
To address private item from a CPU simple arithmetics should be used:
item = (type *)((char *)base + sizeof(struct pcpu) * curcpu)
These arithmetics are available as zpcpu_get() macro in pcpu.h.
To introduce non-page size slabs a new field had been added to uma_keg
uk_slabsize. This shifted some frequently used fields of uma_keg to the
fourth cache line on amd64. To mitigate this pessimization, uma_keg fields
were a bit rearranged and least frequently used uk_name and uk_link moved
down to the fourth cache line. All other fields, that are dereferenced
frequently fit into first three cache lines.

The scope of these callbacks is primarily to support actions that affect the
taskqueue's thread environments. They are entirely optional, and
consequently are introduced as a new API: taskqueue_set_callback().
This interface allows the caller to specify that a taskqueue requires a
callback and optional context pointer for a given callback type.
The callback types included in this commit can be used to register a
constructor and destructor for thread-local storage using osd(9). This
allows a particular taskqueue to define that its threads require a specific
type of TLS, without the need for a specially-orchestrated task-based
mechanism for startup and shutdown in order to accomplish it.
Two callback types are supported at this point:
- TASKQUEUE_CALLBACK_TYPE_INIT, called by every thread when it starts, prior
to processing any tasks.
- TASKQUEUE_CALLBACK_TYPE_SHUTDOWN, called by every thread when it exits,
after it has processed its last task but before the taskqueue is
reclaimed.
While I'm here:
- Add two new macros, TQ_ASSERT_LOCKED and TQ_ASSERT_UNLOCKED, and use them
in appropriate locations.
- Fix taskqueue.9 to mention taskqueue_start_threads(), which is a required
interface for all consumers of taskqueue(9).

This change allows creating file descriptors with close-on-exec set in some
situations. SOCK_CLOEXEC and SOCK_NONBLOCK can be OR'ed in socket() and
socketpair()'s type parameter, and MSG_CMSG_CLOEXEC to recvmsg() makes file
descriptors (SCM_RIGHTS) atomically close-on-exec.
The numerical values for SOCK_CLOEXEC and SOCK_NONBLOCK are as in NetBSD.
MSG_CMSG_CLOEXEC is the first free bit for MSG_*.
The SOCK_* flags are not passed to MAC because this may cause incorrect
failures and can be done later via fcntl() anyway. On the other hand, audit
is expected to cope with the new flags.
For MSG_CMSG_CLOEXEC, unp_externalize() is extended to take a flags
argument.
